Running into an issue in implementing Closed Captions in a Javascript UWP application. We use a manual Closed Caption implementation (because of cross-platform reasons).

I have implemented all the various user settings, like ClosedCaptionSize, ClosedCaptionStyle etc.

However, I seem to be missing the specific property or value to check if the user has actually enabled Closed Captions in his or her account.

The docs do not give any information other than how to style the captions. I had expected it to be present in the namespace of the aforementioned docs (Windows​.Media​.ClosedCaptioning) but that doesn't seem to be the case.

How can I determine if the user has enabled or disabled Closed Captions?

There isn't a way to do this. Media closed captioning is enabled per video not system wide. Ref How to modify the closed captioning settings on your Xbox One console

The app hosts the video if using a custom captions renderer is responsible for toggling on and off(offering UX). Built-in platform controls are bound by default to enable our system renderer.

If the app wants a different behavior we can override the button in XAML but for a JS app we will have to provide their own controls since that kind of selective extension is not part of W3C.
